A Novel Approach to Enhance Crude Oil Recovery Ratio Using Selected Bacterial Species

The high viscosity and low flow properties of some crude oil make them difficult to extract from oil reservoirs. This study investigated the mechanisms responsible for the enhancement of oil recovery using fractured dolomite core models. Bacterial strains, <i>Nocardia cyriacigeorgica</i>...
